The axle nut has a high torque rating, so it's generally fairly difficult to remove. If you have a good impact gun, it may be time to break it out, otherwise you'll need a large breaker bar and probably want to leave the wheel on, with the full vehicle's weight keeping the wheel from rotating.

Torque the Axle nut to spec.

The Syclone/Typhoon supplemental manual says 181 ft-lbs.

The 4wd Sonoma/Jimmy variants looks like its 160 ft-lbs.
